Model A results
==============================


Tested sizes and results
------------------------------

We test the components :math:`\mathrm{yy}` and :math:`\mathit{xy}` of the element that correspond to the normal and tangential components of the local law of behavior in the interface, using the constraint field SIEF_ELGA as well as the damage value :math:`{D}_{T}` (which corresponds to the second variable of the field VARI_ELGA). The values are tested at the Gauss point 1 of the joint element, at 4 different time steps: at the beginning of loading, during the growth phase of the damage, after the peak of the maximum bond strength and at the end of the loading.
